ROLLING MILL.

Specification of Letters Patent To all whom it may concern:

Be it known that l, VICTOR E. EDWARDS, a citizen of the United States, residing at \Vorcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in llolling-ldills, of which the following is a SpCCll'lCatlOn, accompanied by drawings forming a part of the same, inwhih- Figure 1 represents a plan View ofa series of pairs of rolls for the consecutive reduction of a rod, and forming the finishing rolls in a. continuous rolling mill. Fig. 2 is a transverse sectional view on alarger scale, and Fig. 3 is a detached View of the roll supporting turntable.

Similar reference letters and figures refer toSimilar parts in the different views.

The object of my invention is to provide means for bodilyftransferring from their operative'position in acontinuous mill, one or more pairs of finishing rolls with their housings, and substituting thereforother pairs of rolls with their'housings by a single operation.

Referring to the accompanying drawings 1 denotes the final pair of rolls in a series of pairs for the consecutive reduction of a rod and forming a .continuous reducing mill.

2 and 3 denote pairs of finishing rolls, rolls 2 being arranged to'receive the rod from rolls 1 through a curved trough or r'e peater 4. .From-rolls 2-the rod is delivered through a curved repeater 5 to the last pair of finishing rolls 3 which give to the rod its final dimensions and which deliver it to a conveyor or to a cooling bed 6.

It is sometimes necessary to replace the rolls 2 and when they become worn, or to exchange them for other rolls, giving slightly different dimensions to the finished rod. To remove the rolls 2 or 3 from their housings and substitute others requires a prolonged interruption of the mill, and itis the purpose of my present invention to provide means for effecting this exchange by a single operation, and without seriously interrupting the workof the mill. 1 accomplish this result by mounting the roll housings of the'rolls 2 and upon a bed plate 7, preferably driving the rolls independently from the remaining rolls of the continuous mill, by means of an electric motor 8, located at. the end ot and in alinement with the roll shafts. The motor 8 and bed plate Tare supported upon a turn table 9, mounted upon the upper end of the plunger 10 of a hydraulic elevator which enables the table 9 to be raised and lowered. Mounted upon the table 9 is a second bed plate 11 supporting the roll housings of rolls 12 and 13, and

also an electric motor 14 operatively connected with the rolls 12 and 13. The under side of the table 9 is provided with lugs 15, 15, having oblique or beveled sides and adapted to engage similarly shaped recesses 16 in the stationary blocks 17, by which the table 9 is held-from rotative movement. when in its lowest position, in which position the rolls supported upon the table arebrought into the proper horizontal plane to cooperate with the repeaters connecting the rolls with the other pairs in the continuous mill.

When itis desired to shift the finishing rolls, the table 9 raised sutfieiently to re lease the locking lugs 15 from the stationary blocks 17, which enables the table to be ro- Patented July 2,1912,

tated one hall a revolution. 'It is then lowered to bring the locking lugs 15 into engagement with the blocks 17, thereby looking it in position. This operationoarries the rolls 2 and 3 into the position occupied by the rolls 13 and 12 in Fig. 1, and carries the rolls 13 and 12 into the position occupied by the rolls 2 and 8 in Fig. .1, and in proper position to cooperate with both the rolls 1 and the cooling bed 6.

The shifting of the finishing rolls as described above, requires but a short period of time and occasions no material delay in the operation 01 the mill. If it becomes necessary to change the rolls in the housings owing to the wear of the grooves, or to substitute other rolls having grooves of difi'erent dimensions, the exchange of rolls can be made ii" the pair of housings which are out of commission and during the time that the other pairs of rolls are in operation, without causing any interruption in the work of the mill, for example, the rolls 12 and 13 can be taken from their housings and other rolls substituted therefor while they are in the position shown in Fig. -1, without interrupting the operation of rolls2 and 3.

In Fig. l I have shown two sets of rolls only, each containing two pairs of rollsand mounted upon diametrically opposite sides of the table 9, giving duplicate sets of finish ing rolls, as this number fulfils the usual requirem'ents'in rolliiig'inill practice, but if desired, three or even four sets of roll housings may be mounted upon the same table, and the locking lugs 15 so arranged as to lock either set in operative position.

By the use of independent motors I can put either set of rolls into motion, if desired, for any purpose, independently of their position relatively to the remaining rolls of the mill, and I avoid the necessity of con necting and disconnecting the several sets of rolls from a common motive power..

I claim,

1. A rolling mill, comprising a pair of reducing rolls, a support for rolls rotatable about a vertical axis, separate sets of rolls mounted on the upper surface of said support and in the same horizontal plane, each set arranged to be brought into and out .of operative relation with said reducing rolls by the rotation of said support.

2. A rolling mill, comprising a support rotatable about a vertical axis, a pair of rolls mounted on the upper surface of said support, with saidsupport arranged to be rotated to bring said pair of rolls into and out of operative position as desired.

3. A rolling mill, comprising a horizontal support, with a pair of rolls mounted on its upper surface, with said support arranged to be rotated to bring said pair of rolls into and out of operative position as desired, and means for holding said support in a stationary position.

4. A rolling mill, comprising a support rotatable abouta vertical axis, independent pairs of rolls mounted on said'support, with said support arranged to bring b its rotation each independent pair of rol s into operative relation with the remainder of the rolling mill, and means for holding said support in a stationary position.

5. A rolling mill, comprising a support rotatable about a vertical axis, independent pairs of rolls mounted on the upper surface of saidsupport, a curved trough or repeater leading from a stationary pair of rolls, and means for raising and lowering said support to bring the rolls mounted thereon into the proper horizontal plane to cooperate with said repeater. I

6. A rolling mill, comprising a horizontal support rotatable about a vertical axis, separate sets of rolls mounted on the upper surface of said support, with said support arranged to be rotated to bring each set of rolls into and out of operative position, and independent means for operating each set of rolls on said support.

7. A rolling mill, comprisin a support rotatable about a vertical axis, independent pairs of rolls mounted on the upper surface of said support, with said support arranged to be rotated to bring each independent pair for insuring the of rolls into operative relation with the remainder of the rolling mill, means for raising and lowering said supportto bring the rolls mounted thereon into the proper horizontal plane to cooperate with the remainder of the mill, an means for holding said support from rotation in said proper horizontal plane.

8. A rolling mill, comprising a pair of rolls held in a stationary position, a horizontal rotatable turntable with a pair of rolls mounted thereon, with said turntable arranged to bring by its rotation said rolls mounted thereon into operative relation with said stationary rolls, meansfor maintaining said turntable in said operative position, comprising a stationary block, a lug on said table arranged to engage said block when said table is in said operative'position, and means for raising said table to disengage said lug from said block.

9. A rolling mill, comprising a pair of rolls held in a. stationary position, a horizontal rotatable turntable with a pair of rolls mounted thereon, with said turntable arranged to bring by its rotation said rolls mounted thereon into operative relation with said stationary rolls, means for maintaining said turntable in said operative position, comprising a locking mechanism arranged to operate when said table is in operative position, and means for raising said table to disengage said locking mechanism.

10. A rolling mill, comprising a horizontally rotatable support, with a air of rolls mounted upon the upper sur ace of said support, with said support arranged to bring by its rotation'said rolls mounted thereon into operative position, and means for holding said support from rotation and correct operative position of said rolls.

11. A rolling mill, comprising a horizontally rotatable support, with a pair of rolls mounted on the upper surface of said support, with said support arranged to bring by its rotation said rolls mounted thereon into operative position, means for maintaining said support with said rolls in said operative position, comprising a stationary block having a recess with oblique or beveled sides, a similarly shaped lug on said support arranged to engage said recess and thereby bring said rolls into operative position, and means for raising and lowering said support to bring said rolls 'into the proper horizontal plane.
